Procedure

Potassium carbonate (5.2 g) was added to a DMF solution (50 ml) of 4-hydroxy quinoline (5.0 g) and the mixture was stirred. Iodine (9.6 g) was added to the mixture, followed by stirring at room temperature for 3 hours. A saturated sodium hydrogencarbonate aqueous solution (73 ml) of 25% sodium sulfite, and water (50 ml) were added to the reaction mixture. The mixture was stirred and the precipitated insoluble matter was separated. The filtrate was washed with water and dried to give the title compound (9.0 g) as a white powder.
